ProTrac* is designed as an upgraded fly-bar system for the theatre or related fields, with several extra options.

New developments within the theatre branch have led to new demands on the existing fly-bar systems. A combination of higher loading requirements, due to a growth in the size of productions, and the introduction of the mechanical operated fly-bar systems, have made the existing fly-bar system, in many cases, not suitable for the job. ProTrac has been developed to fill this gap.

If the uniformly distributed load needs to be upgraded from 300 to 500 kg and the point load from 40 to 150/200 kg the normal fly-bar does not have the required strength. Therefore, the single round tube is often replaced with ladder beams, usually made from steel. ProTrac offers a better alternative than these steel ladder beams, being specially designed to meet the demands from a modern theatrical environment.

ProTrac is a combination of an aluminium extruded rectangular profile underneath which a round tube of 60 mm or 48,3 mm is attached. Suspension points slide into the square profile and can be locked at any desired place.
